Ring terminal Ergom KOR 25/12 copper tinned – model E11KM-01020103700 (for 25 mm² to 12 mm stud)

Ring terminal Ergom KOR 25/12 is a tin‑plated copper cable lug designed to be crimped onto a 25 mm² conductor and fitted onto a 12 mm stud or bolt. The tin plating improves corrosion resistance and ensures stable electrical contact in automotive, industrial and general electrical installations where a secure ring connection is required.

Advantages

The tin‑plated copper construction combines good conductivity with enhanced corrosion protection, reducing the risk of contact degradation over time. The ring design provides a reliable mechanical and electrical connection to studs or bolts, and the lug is sized to accept a 25 mm² conductor for common power and grounding applications. The smooth internal barrel and consistent crimp geometry facilitate effective crimping with compatible tools, helping to produce repeatable, low‑resistance terminations.

Suitable for

• Automotive battery and grounding connections
• Industrial control panels and power distribution
• Electrical installations requiring reliable stud-mounted terminations
• Marine and outdoor equipment with tin‑plated corrosion resistance needs

Key specifications

• Conductor cross‑section: 25 mm²
• Stud/bolt diameter: 12 mm
• Material: copper with tin plating
• Connection type: closed ring lug for crimp termination
• Typical applications: power, grounding, and stud-mounted connections

How to use

Strip the conductor insulation to the manufacturer‑recommended length, insert the bare conductor fully into the lug barrel, and crimp using a properly sized crimping tool or hydraulic press to achieve a secure mechanical and electrical connection. Place the ring over the 12 mm stud or bolt and fasten with an appropriate nut and washer, ensuring the connection is tight and free from insulating material between mating surfaces. Inspect the crimp and the bolted connection for mechanical integrity and proper contact before energizing the circuit.

Usage recommendations

Use a crimping tool matched to the 25 mm² lug size and inspect crimps for correct compression and absence of conductor strands outside the barrel. For outdoor or corrosive environments, ensure washers and mating hardware are compatible with tin plating to maintain long‑term corrosion resistance. Follow applicable electrical standards and torque specifications for the 12 mm stud when fastening.
